No. 839,391. Specification of Letters Patent.

' Patented Dec. 25, 1906. Application filed March 8, 1906- Serial No.304,842.

I serve to prevent said traveler from jumping Belt known that I, EMIL M.KEHR, a citlthe track. zen of the United States, and a resident ofatertown, in the county of Jefferson and heads being in screw-threadedconnection with said hangers. The horizontal tubular tion thereof. lowerend 7' of each hanger serves as a bearing My invention consists incertain peculiarlfor a trunnion 7c of the dump-box H of the constructionand combination of parts carrier.

i Held by set-screws m in vertically-adjusted osition on the dump-boxhangers are collar-brackets I, to which the lower ends of cables J arefastened, and the other ends of these cables are fastened to a drum 'K,suspended in hangers L, attached to the beam E usted position, therelative arrangement of of the traveler central of the same, saidcaparts being such as to provide against interbles being-trainedon'rollers M, suspended in of the dump-box latch with the tilt of hangerextensions of the clips d aforesaid. is retracted from its of the drumis a'crank N following is afull, clear, and exact descripelevatedcarriers, each having vertically-adjustable dump-box hangers that arevirtually movable sections of a bail constituting part of a traveler andrigid with the same in ad l Fasten a journal and a ratchet-wheel O, ade'tent n being hung in connection with'one 'of the hangers L to engagewith said wheel, the whole constituting a winch.

One of the brackets I guide extension 19 for the vertical shank of alatch P, and another collar-bracket I, held by a set-screw m in adjustedposition on the adjacent dump-box hanger, is also provided with a guideextension p for said shank of the latch. v u A cord, flexible wire, orcable Q, in connection with the upper end of the latchshank', is trainedon one of the rollers M and connected to the drum K to wind thereon orunwind therefrom with the cables J, and the horizontal footg of thelatch is engageable with a keeper 1*, attached to the adjacent end ofthe dump-box. The latch pull device runs through an end eye of anangular foot 8 of the tripper B, that has a horizontal offset head t andis provided with vertical slots engaged by guide-lugs u, extending fromarms 1) of one of the depending branches 0 of the housing D aforesaid. Aweighted lever B is fulcrumed in connection with the beam E of thetraveler and connected to the tripper B return the same to normalposition after bemg depressed by a contact of its head twith the cam b,that depends from the track A, above specified.

From the foregoing it-will be understood that the-vertical adjustment ofthe dumpbox is effected by means of the winch above eeper.

A further object of my invention is to provide for simultaneousadjustment of a latchautomaticpredetermined trip of the latch.

The accompanying drawing represents a; perspective view of an elevatedcarrier in accordance with my invention suspended from a track providedwith an obstruction in the;

is provided with a stituting part pf the latch-trip mechanism of thecarrier, parts of said carrier being broken away and in section. 7

Referring by letter to the drawing, A indi" my improved elevatedcarrier, this track being provided with a depending stationary cam 19 inthe path of a tripper B, constituting part of a latch-actuatingmechanism hereparticularly described. Supported on the track is atraveler comprising a pair of trolley-wheels O, a housing D, in whichthe wheels are hung, a beam E, bolted to deending branches 0 of thehousing, and a bail 1 held by clips (1 on the beam, these clips I beingriveted or otherwise rigidly secured to said beam. The ends of the beamare notched for the engagement of the bail that l is thus prevented fromswaying, and clamping-nuts e are run on stay-bolts f, run through saidbeam adjacent to the end notches of same. Opposite its branches thehousing D of the traveler is provided with depending guard projectionsg, that with said branches disengagement of the specified, and thelatch-pull device is kept taut by the same means. The hangers for thedump-box being virtually adjustable sections of the bail of thetraveler, they are very rigid in adjusted position, and there being nospring, interference of the latch with the automatic tilt of said boX isavoided. The traveler, with a loaded dump-box, being run out on thetrack, the contact of the tripper with the depending cam of said trackwill result in a bend of the latch-pull device and a latch from itskeeper, whereupon said dump-box is free to tilt. The weighted leveroperates to return the latch-pull device and latch to normal position,and the dump-box being swung into like osition there is automaticengagement of v said latch with its keeper.

1. An elevated-carrier traveler comprising a bail having end collars,tubular dump-box hangers fitting the collars, and bail-engaging heads onthe hangers.

2. An elevated-carrier traveler comprising a bail having end collars,tubular dump-box hangers having sliding .flt on the collars,bailengaging heads on the hangers, and means for lifting the hangers onsaid bail and holding the same in adjusted position.

' 3. An elevated-carrier traveler comprising a bail, rollers and winch;dump-box hangers in telescopic engagement with the bail, cables trainedon the rollers and connecting the drum of the winch with brackets ofsaid hangers, a dump-box latch, a flexible pull device for the latchtrained on one of said rollers and connected to the winch-drum, a detentarranged to engage a ratchet-wheel in connection with said drum, atripper in connection with the traveler and latch-pull device, and atripper-actuating device in connection with the track for said traveler.

4. An elevated-carrier traveler comprising a beam notched at its endsand a bail in connection with the beam to engage the end notches thereofdum -boX hangers constituting continuations oi the bail, a dump-boxlatch, guides for the latch in connection with one of said hangers, aflexible latch-pull device, a tripper in connection with the travelerand latch-pull device, and a tripper-actuating device in connection withthe track for said traveler.

5. An elevated-carrier traveler comprising a beam, a bail on the sameand a winch and rollers suspended therefrom; dump -bo.\' hangers intelescopic engagement with the bail, cables trained on the rollers andconnecting the drum of the winch with brackets of said hangers, adump-box sliding latch and guides for the same, a flexible )ull devicetrained on one of said rollers an connected. to the winch-drum, a detentarranged to engage a ratchet-wheel in connection with said drum, atripper having vertically-reciprocative connection with the traveler andconnected to the latch-pull device, a weighted lever connected to thetripper and fulcrumed in connection with the traveler-beam, and atripper-actuating device in connection with the track for said traveler.

In testimony that I claim the foregoing I have hereunto set my hand, atVVatertown, in the county of Jefferson and State of VVisconsin, in thepresence of two witnesses.
